DisclaimerUnofficial, and not affiliated with Anthropic. Nearly all of this is read straight out of what ships: npm bundles, captured prompts, published docs. Anthropic's own notes go in verbatim, marked as theirs. The rest is my reading, and every entry carries the strings behind it. If one looks wrong, vote it down and say why.

Plugin Binary Asset Provisioning

Feature flag
tengu_plugin_binary_assets Off in both readings

The flag server returned off for the account this site reads and for the anonymous baseline. A reading of off cannot rule out a rollout these two readings sit outside of.

These values were read against a different version of Claude Code, so treat them as the nearest reading available instead of one taken on this release.

Read once, for one account on one subscription tier, against v2.1.196. It isn't a statement about your account. What a flag value here can and cannot tell you

Plugins that declare a binaries manifest section can now have their binary assets automatically downloaded and installed into the plugin's bin/ directory.

Details
  • Controlled by CLAUDE_CODE_PLUGIN_BINARY_ASSETS env var or tengu_plugin_binary_assets feature flag. [Gradual Rollout]
  • Each entry in binaries maps a basename to a SHA-256 hash; only the first 10 entries are provisioned per pass.
  • Downloads are cached by hash to avoid redundant network requests.
  • Binary files must remain within the plugin directory (path escape is rejected).
  • The binaries key must be an object mapping basenames to { sha256 }; invalid entries are skipped with a warning.
Evidence

New provisioning system (search for "[pluginBinaryAssets]" and "binary asset provisioning failed")

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
